Specication forming part of Letters Patent No. 126,600, dated May 7,1872.

To all whom it may concern:

Be it known that I, LOUIS W. WERNER, of

` St. Louis, in the county of St. Louis'and State of Missouri, have madecertain new and useful Improvements in Aero Steam-Generators: and I dohereby declare the following to be a full and true description thereof,reference being had to the accompanying drawing and to the letters ofreference marked thereon.

The object of this invention is to achieve a i Iimore ready and greaterpower to operate the pumps, chieliy ot' steam tire-engines, and thenature of this invention relates to the arrangement of air-pumps, incombination with the boiler; said air-pumps being operated by aneccentric attachment Secured to the Wheels of the engine, and by whichatmospheric air is forced into the boiler through the heating andcirculating pipes, in manner now to be more fully described.

To enable those herein skilled to make and use my said improvements Iwill now more fully ldescribe the same, referring to- Figure l as a sideelevation, and Fig. 2 as a sectional plan at line m x.

The steam-boiler A having heating and circulating coils A', as usual, isproperly supported on wheels B. The air-pumps C are arranged on bothSides, and attached to the boiler, being supported by rubber or othersuitable sprin gs. To the Wheels B are secured properly an eccentricattachment, B', consisting of the eccentric b, which communicates motionto the plunger of the pumps C by means of the connecting-rods b1 andbeams b2, as shown in Fig. 1. Connected with pumps C is adischarge-pipe, D, which communicates with a branch-pipe, D'. The pipeD' passes through the outer shell of the boiler, and extends a shortdistance into the end of the coils A', an annular space, a, being leftbetween the outer periphery of the pipe D' and the inner periphery ofthe coil A', as indicated in Fig. 2, the object of this manner ofconnection being to cause a quicker circulation of the water in thecoils, when the air is forced into same; and, further, when theair-supply is shut oiI' the Water can freely pass into the coils fromthe boiler. The pipe D has stop-cock d to let on or "shut off the Supplyof air to the boiler. The blower-pipe E connected to the pipe D' passesdown underneath the gratebars of the boiler, the blowing-action of saidpipes being regulated by a stop-cock, e.

The motion of the air-pumps, derived from the supporting-Wheels of theengine, causes and forces with pressure the Water through the coilsofthe boiler in a quicker manner, producing a better circulation thanordinarily achieved.

After arriving at the fire the pumps can be disconnected from theengine-wheels, and connected and operated by the cam or eccentric oftheengine. A small engine can also be supplied and arranged, to which thepumps can be connected so as to operate during the fire, as required.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The arrangement of air-pump C, eccentric B', Wheels B, pipes D D', asand for the purpose set forth.

2. The arrangement of air-pump C, eccentric B' b b1, Wheel B, pipes D E,as and for the purpose set forth.

3. The arrangement of air-pump C, eccentric attachment B', pipes D 1)'E, stop-cocks d and e, in combination with the boiler A, as and for thepurpose set forth.

4. The nozzle or pipe D', formed tapering at its inner end, as shown,when arranged with coils A', pipe D, and air-pump connections, tooperate as and for the purpose set forth.

In testimony of said invention I have hereunto set my hand.

LOUIS W. WERNER.

In presence of- WILLIAM W. HERTEEL, ROBERT BURNS.
